This article investigates a new Hybrid Posicast Controller (HPC) for Fundamental Positive Output Super-Lift Luo Converter (FPOSLLC) in Continuous Conduction Mode (CCM). It is a feedforward controller that decreases the flippantly damped plant overshoot in the step result. However, because of fluctuations in the natural frequency, the traditional controller technique is sensitive. In this article, a novel HPC is built to alleviate the FPOSLLC’s undesired sensitivity and load voltage control. HPC has a feedback loop and a posicast structure. The main design function of posicast is its independent computational time delay. By creating a MATLAB/Simulink model, the FPOSLLC implementation with HPC may be verified under various operating conditions. In comparison to standard PID control, the results of the new HPC have produced little noise in the control signal.

“…While the equations derived using the SFG method are straightforward, the method's lack of dynamic detail results from the modeling technique in averaging the high-frequency components Which will render the controller unsuitable for large-signal dynamic control. In [12], it was stated that a dc-dc converter's performance might be improved by using a sliding mode controller with a changeable structure. However, it only functions optimally under certain conditions and cannot provide the same dynamic reaction as a switching converter in a saturated zone.…”

Positive-output super-lift Luo converters (POSLCs) with low switching losses are the subject of this paper's analysis, design, and regulation. Due to their ability to boost voltage at higher levels, converter switching devices are rarely put under extreme voltage conditions. The input voltage to an active switching device is typically lower than the output voltage. This means that low-quality components are used to build the converter. The proposed conversion can be a good choice in PV micro converter applications requiring high voltage gain. The continuous conduction mode of the converter and its underlying operating principle and steady-state analysis are described. The converter's basic principle is demonstrated by constructing a working hardware prototype, which is tested in the lab. The outcomes demonstrate the benefits of employing an Arduino for voltage control. It has also been found that the converter achieves maximum efficiency of 95.3% at full load. The results were confirmed using MATLAB / Simulink in POSLC design with MPPT which is in agreement with the experimental results.
